Abstract: @ A battery cell and a method for preparing a battery cell are disclosed in which a substantially fixed volume container includes the cell components therein in voltaic relationship, with the cell components including an anode comprising lithium metal, a non-aqueous electrolyte and a cathode in a spatial relationship to the anode within the fixed volume container, wherein the cathode comprises cathode active material which upon discharge intercalates lithium and undergoes a phase transition to a distinct structural phase in which phase the cathode active material can reversibly operate and which phase provides a cathode expansion greater than the anode volume decrease upon discharge, and wherein the spatial relationship and the cathode expansion within the substantially fixed volume are sufficient to produce a compressive load on the anode which inhibits the formation of a porous deposit of exterior, irregularly oriented, amalgamated lithium grains on the anode when the cell is reversibly operated with the cathode in said phase.

Abstract: A stack mold (10) for injection molding having a pair of mold halves (11 and 12) movable toward and away from each other along an axis of movement and in which a plurality of mold plates (13) are arranged parallel to one another between the mold halves and parallel to the axis of movement of the mold halves. This arrangement of the mold plates (13) permits a mold area in excess of the platen area and enables a larger number of large thin parts to be simultaneously molded in a given size press than is possible in the prior art. Further, the mold plates (13) are formed with hangers (33) which support the mold plates (13) on the mold halves (11 and 12), enabling different mold plates (13) to be easily substituted without disassembling the mold structure and slides (27 and 28), and also eliminating the need for guide pins or pillars for the mold plates. The mold plates (13) are supported on program plates (22 and 23) having guide surfaces (24, 25 and 26) thereon for determining the opening and closing sequence of the mold plates (13) during opening and closing movement of the mold press, and the central portion of the endmost mold plates or slides (27 and 28) is wedge shaped. This structure also eliminates the need for guide pins or pillars for the mold plates (13).

Abstract: A freight container of generally cuboidal shape includes a pair of sides (3) which define the lateral extremities of the container and extend between ends (1, 2) of the container. The exterior surfaces of the pair of sides are spaced apart by a greater distance along their middle portions (15) than along their end portions (16), whereby the overall width of the container is less at the end portions than at the middle portions. The container is therefore able to have an increased capacity for a given size of each end.

Granted: 1988-12-01
Abstract: A beverage dispensing system and distributing process with such a system has a flexible bag 1 containing the beverage which may have carbon dioxide dissolved therein. The beverage is drawn off through a pipe 3 (assisted by a pump 8) for dispensing through nozzle 5 having a tap 6. Carbon dioxide, nitrogen (or other inert gas) and/or air gases are introduced into the beverage through a passage 11 by way of a fixed orifice restrictor 12 and a non-return valve 13. The pressure of the gas which is introduced is adjustable at 14 and baffles 15 can provide turbulence in the beverage during dispensing to promote the dissolution of the introduced gas therein. The facility to introduce the gas or gases permits the beverage in the bag 1 to have a low content of carbon dioxide so that the bag collapses under atmospheric pressure while the beverage as dispensed is additionally gasified for the formation of a froth or head.

Abstract: Concrete consists of cement (10), gravel (6, 6a, 6b), aggregate and water. To increase the tensile strength, part of the aggregate is replaced by longitudinal reinforcing elements (1, 11, 12, 17), which are added before or during mixing. When the concrete sets, these are then anchored in an arbitrary spatial arrangement in the structure. To avoid segregation of the raw concrete due to gravity, the density of the reinforcing elements (1, 11, 12, 17) is selected so as to correspond to that of the raw concrete. This concrete exhibits a high tensile strength in all directions. This strength may be increased by using reinforcing elements (1, 12) with curved ends, whereby the curvature radius corresponds preferably to that of the grain (6) which is enclosed in the concrete. By selecting the material for the elements and as applicableby varying the filling of the voids, the atomic or nuclear properties of the concrete can be adapted to the required values.
